During the seven-year period from 1976 to 1982, we treated 1 366 consecutive patients with blunt eye trauma. Using the final visual outcome in our patients and some practical considerations, we have classified the diverse spectrum of entities produced by blunt eye trauma to indicate their prognostic value. Pre-ocular haematoma, sub-conjunctival haemorrhage, lid injury, lacrimal apparatus injury, corneal abrasion, conjunctival tear and moisis are classified to carry a very favourable visual prognosis, while prognosis was favourable for orbital injury, grade I hyphaema and lens injury that is not associated with hyphaema and mydriasis. Grade II hyphaema and macular oedema indicate a poor visual outcome, and grade III hyphaema, lens injury associated with mydriasis and hyphaema, mydriasis, vitreous haemorrhage, macular haemorrhage, indirect choroidal rupture and optic nerve damage indicate a very poor visual outcome. The triad of grade III hyphaema, mydriasis and a total cataract is considered as the most unfavourable prognostic indicator of visual outcome in blunt eye trauma. Our main purpose in this study of evolving a prognostic classification of entities produced by blunt eye trauma is in the hope that this classification will serve as a valuable guide to specialists as well as to non-specialists involved in ophthalmic care services.
